ROAD-BED-BUILDING MACHINE.

Application led September 22, 1926.

My present invention has reference to a railway road bed building machine and has for its primary object the provision of means for simplifying and improving the existing 6 art by the provision of a machine for this purpose, whose action` throughout is automatic and which embodies means for elevating the track, depositing dirt for the bed beneath the raised track, and thereafter loweringl the track onto its bed, the machine traveling the entire length of the track.

A further ob] ect is the provision of a railroad bed building machine which will duispense with the use of the trestles ordinarily employed in this connection, the said trestles having their top portions disposed over the track, the dirt cars traveling onto the trestles, therefrom through the trestles onto the track, the process requiring manual labor in elevating the track and thereafter tamping the dirt to provide the bed for said track.

A further object is the provision of a railroad bed building machine by whose use the bed for a railway track may be constructed in an easier manner than has to my knowledge heretofore been attempted andl with a less employment of manual labor.

To the attainment of the above broadly stated objects and many others which will present themselves as the nature of the invention is better understood, the improvement further resides in certain novel features of construction, combination and operative association of parts, a satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings:

Serial No. 137,160.

Figure 10. is a detail sectional view ap'- proxiniately on the line 10 .1() of Figure 2. In carrying out my invention, I make use of a frame that comprises longitudinal bars or plates connected by transverse bars or plates 1. Journaled throughl suitable bearings at the ends of the longitudinal plates or sides 2 of the frame there aie shafts` 3 8 upon whose ends there are fixed wheels 4. The wheels are peripherally cogged, and engage in suitable notches in the links 5 of endless caterpillar chains. Supported on the frame, to one side of one of the caterpillar chains, there isa motor 6, and this motor is hitched to one of the shafts 3, whereby to infipart motion to the caterpillars and consequently to the frame. Suitable control means 7 is provided for the motor, whereby the same may be stopped, started, thrown into reverse or the speed thereof regulated.

Supported centrally on the top of the frame of the caterpillar, there is an open frame in the nature of a platform or bridge. This bridge includes parallel side members 8 of a length greater than that of the caterpillar frame. The side members 8 are connected by transverse members 9, and on one of these members 9 there are upper and lower laterally extending plates 10 and passing through an opening in' the projecting ends of these plates there isa headed pin 11. This pin passes through an opening in one of the transverse members 9` of the caterpillar frame. As disclosed by Figure 4 of the drawings, the opening in the member 9 of the frame has its bore inclined inwardly from its ends to its center, so that the shoulder 12 provided at the center of the said bore contacts with the pin 11. A transverse element, such as a Cotter pin 13, passes through the end of the pivot pin 11. In this man ner it will be noted that the bridge is pivotally associated with `the caterpillar frame.- The side members 8 of the bridge have their ends inclined downwardly, as indicated for distinction by the numerals 14. The extremities of the inclined portions 14 of the bridge have hingedly secured thereto, as at 15. inwardly directed plates 16, Vand fjournaled on the outer end of each-of the plates 16 there is a flanged roller 17. The plates 16 that provide the mounts for the rollers are iniuenced by springs 18 secured on adjustable means 19 that are connected to the inturned extremities of the angle ends 14 of the bridge.

Extending inwardly from the sides 8 of the bridge, at spaced intervals throughout the length of the said sides there are stub shafts on which are mounted grooved wheels 20, and on the ends, adjacent to the lower ends of the inclined portions 14 of the bridge, there are other inwardly directed stub shafts 2l on which there are journaled sprocket wheels 22. Around these sprocket wheels and guided between the flanges of the rollers there are endless sprocket chains 23. The sides of the bridge have depending brackets on which are journaled stub shafts of grooved wheels 24- that support the lower lead of the endless sprocket chains 23.

Suitably supported on the downwardly inclined ends 14 of the sides of the bridge,

`'at the forward end of the device, there are outwardly extending platforms 25, respectively. Journaled through suitable bearings in the platforms 25 there are posts or rods 2G having wheels 27 fixed on the upper ends thereof. Beneath the platform each rod 26 has fixed thereon a flat disc or wheel 28, and each of these discs or wheels is provided with spaced apertures 29. Supported from each platform 25 and movable through one of the openings 29 there is a member 30 that carries a. pin 3l that is designed to pass through one of the said openings 29. The under face of the wheel or disc 2S is provided with spaced ears 32, and lixedly secured between these ears there are scraper blades 33.

On the side members 8 of the bridge there are secured brackets 34, Fig. 9. The brackets are in the nature of angle members and have their outer and widened ends formed with sockets through which pass the shanks or stems for the mounts 36 of rollers 37. 'llhc shanks 35 are threaded and the socket portions of the brackets 34 are notched for the reception of toothed wheels 38 that have threaded bores to engage with the shanks 35. The wheels 38 have their teeth engaged by the teeth of worms 39, the shafts 40 for the worms being suitably ournaled through the brackets and through other bearings on the sides of the bridge, and the outer ends of these shafts are cranked, as at 4l. By this arrangement it will be noted that the bridge may have its forward end raised or lowered with respect to the frame for the caterpillar, and by mounting the scrapers 33 as above described itwill be apparent that the same may be disposed in proper angle relation to sweep or force dirt beneath a track.

The operation of the improvement may be briefly des ribed as follows: It is, of course to be understood that the tractors of the caterpillar are of a materially greater dish tance apart than the rails 42 of the construction track, and also that the ends of the said rails 42 are connected together and the said rails are spiked on ties 43. Dirt is dumped along the sides of the track. rllhe endless chains 23 are spaced a distance apart less than the length of the ties 43. The rollers 17 are also arranged in pairs that are suitably spaced to engage with the inner faces or in the fishing spaces of the rails 42. One end of the track is manually raised so that the rails will be engaged by the rollers 1T and the ties will rest on the endless chains. The tractor is then propelled in the direction of the arrow in Figure 2 of the drawings. This forward movement of the tractor will bring' the track over the entire length of the endless chains and will cause the blades 33 to force the earth beneath the elevated track. As the tractor advances the portion of the track projected through the end of the machine will again rest on the ground. It will be seen that a road bed can be thus made for the entire length of the track in an easy, ei;-

peditious and efficient manner and with no physical labor upon the part of the operator except for the first elevation of the track.

The simplicity of the construction and its many advantages will, it is thought, be apparent to those skilled in the ait to which such invention relates, but obviously l do not wish to be restricted to the details of construction herein set. forth and therefore hold myself entitled to such changes therefrom fairly fall within the scope of what l claim, providing, of course, that the same do not depart from the spirit or sacrifice any of the advantages of the invention.
